international flights. Our first steps in this direction have been the launching of flights from Istanbul to Sivas and New Delhi. In the coming summer season we are commencing flights to Toronto, and Washington DC. Next in line are Oslo in Europe and Casablanca in North Africa. We are also planning to recommence flights to South Africa.
Expansion of our existing fleet is unavoidable if we are to meet passenger demand for increased flight frequency on some routes and flights to new destinations. We are therefore planning to increase the number of aircraft by 30 percent, and at the same time replace our old aircraft, so that our fleet will consist entirely of new planes. The low maintenance costs on new aircraft, combined with high passenger load factors, will reduce overall operating costs.
We have the highest esteem for all of our passengers, and regard it as our primary duty to provide them with the very best service possible. On domestic flights we are introducing Real Business Class service, whereby, as on international flights, the central seat will be left empty to provide maximum comfort for business passengers.
